A Jacobite ring and a scrap of Bonnie Prince Charlie's tartan will auction with an estimate of ?�2,000-3,000 ($3,365-5,048) at Lyon & Turnbull in Edinburgh on August 13.
The Scotsman newspaper reports the piece of plaid is said to have initially belonged to highland chief Cluny MacPherson, who lived with the prince in a cave in the Cairngorm Mountains while hiding from the British.
They fled there in the aftermath of the failed 1745 Jacobite rising.
Colin Fraser, Lyon and Turnbull's head of silver and jewellery, told the publication: "Because they are so different, there isn't much to compare them to and they are very unique.
"We have had various Jacobite items go up for auction in the past but in general they aren't very common. It is very rare for a ring and plaid such as these to be up for sale, so it'll be interesting to see how much they sell for."
